Chronic hepatitis - primarily caused by hepatitis B and hepatitis C viruses - represents a major global health burden, leading to cirrhosis, liver failure, and hepatocellular carcinoma. Despite effective vaccines and curative therapies, millions remain undiagnosed or untreated.

This episode explores:

• Global epidemiology of hepatitis B and C• Modes of tr…

Malaria remains one of the most significant parasitic diseases worldwide, with a disproportionate burden in sub-Saharan Africa. Transmitted by the Anopheles mosquito, malaria reflects the complex interplay between environment, vector ecology, socioeconomic conditions, and health system capacity.

This episode explores:

• Global epidemiology and regional di…

Tuberculosis (TB) remains one of the leading infectious causes of death worldwide, despite being preventable and treatable. Caused by Mycobacterium tuberculosis, it spreads primarily through airborne transmission and disproportionately affects low- and middle-income countries.

This episode examines:

• Global epidemiology and high-burden regions• Latent ve…

HIV/AIDS has shaped modern public health more profoundly than almost any other infectious disease. Since its emergence in the late twentieth century, it has caused millions of deaths, reshaped global health governance, and driven innovation in prevention, treatment, and human rights advocacy.

This episode examines:

• Global epidemiology and regional varia…

Sexually transmitted infections (STIs) remain a significant global public health challenge, with millions of new infections occurring each year. While many STIs are preventable and treatable, persistent stigma, inequitable access to services, and social determinants continue to drive transmission.

This episode explores:

• Global epidemiology of major STIs…

Infectious diseases remain a central pillar of public health practice. Despite advances in vaccination, sanitation, and antimicrobial therapy, communicable diseases continue to shape global mortality patterns - particularly in low- and middle-income countries.

This episode examines:

• Modes of transmission - airborne, vector-borne, waterborne, contact• Ba…

Neurological diseases contribute substantially to global mortality and disability. Conditions such as stroke, dementia, epilepsy, Parkinson’s disease, and neurodevelopmental disorders collectively represent a major and growing public health challenge, particularly as populations age.

This episode examines:

• The global burden of neurological disease• Stro…

Musculoskeletal disorders are among the leading causes of disability worldwide, contributing significantly to years lived with disability across all regions. Conditions such as low back pain, osteoarthritis, rheumatoid arthritis, and osteoporosis impose substantial personal, social, and economic costs.

This episode explores:

• Global epidemiology of muscu…

Oral diseases are among the most common non-communicable conditions worldwide, yet they often remain overlooked in broader health policy discussions. Dental caries, periodontal disease, and oral cancers contribute significantly to pain, disability, and reduced quality of life across all age groups.

This episode explores:

• The global burden of oral disease

Mental health is fundamental to overall health, yet its determinants extend far beyond individual diagnosis. Suicide alone accounts for more than 700,000 deaths globally each year, representing a major public health concern across age groups and regions.

This episode examines:

• The global epidemiology of mental disorders and suicide• Social determinants …
